    <p>Also see closely related function <code><a href="sitepoints_from_any.html">sitepoints_from_any()</a></code>.</p>
<p>This function relies on</p>
<p><code><a href="read_csv_or_xl.html">read_csv_or_xl()</a></code>  and</p>
<p><code><a href="latlon_df_clean.html">latlon_df_clean()</a></code>

<p>A draft function <code><a href="read_and_clean_points.html">read_and_clean_points()</a></code> would a more general way to get points,</p>
<p>but is still work in progress... it is similar to latlon_from_anything()</p>
<p>except it also uses these functions:</p>
<p><code><a href="latlon_from_regid.html">latlon_from_regid()</a></code>,  <code><a href="latlon_from_programid.html">latlon_from_programid()</a></code></p>
<p>and could eventually use  _from_naics() etc.</p>
<p>Even more generally, FIPS and shapefile inputs could be read through a
single wrapper function at some point.</p>
